Why? Because the damn things look so real that it's genuinely creepy, that's why. I mean, watch this animation -- it's rough at a lot of points, but there's a few shots where it looks like the real people acting in there, and it's freaking me the fuck out. Of course, then Batman slaps the Heath Ledger Joker and his heads spins 360 degrees and turns into Jack Nicholson Joker, which I'm pretty sure isn't real, but I'd just prefer not to be this confused first thing in the morning.
